Question

Kahlid wants to buy a board game that costs Rs 501. He has Rs 479. How much more money does he need?

Answer 1

Rs 22 more

Explanation:

Given

`Game = Rs501`

`Saved = Rs479`

Required

The amount needed

The saved amount when added to amount needed (x) must equal to the price of the game

i.e.

`x + Saved = Game`

Make x the subject

`x = Game - Saved`

This gives:

`x = Rs501 - Rs479`

`x = Rs22`
